Shocking service - Red Data/Vodacom

I am very shocked at the terrible service I have received from Red Data and the only reason why I agreed to the contract was because they are affiliated with Vodacom. Firstly, I was charged for services to which I did not agree and then I was charged for data which I should have received on the 1st April but still nothing to date. I was told its a system error and they will notify me via SMS once its working. I emailed support on the 3rd April to query the charges and was told it will take 72 hours to retrieve the recorded telephone calls, its been 6 days. Today I requested that the contract be terminated and I quickly received an SMS confirming this and when I emailed asking for my refunds, was told that the "investigation" will take 21 working days. How did it go from 72 hours to 21 working days to investigate since day 1, its been a complete nightmare???? I would like a response from Vodacom regarding this and want this sorted out ASAP!
